To get Windows 10 reliable, I had to lobotomise the installed software and USB devices.

I am not angry at Microsoft, as they did give me Windows 10 for free! I do feel a little misled about its reliability on older computers never certified for its installation by the manufacturer though.

Windows 7 is on its way to being an obsolete product. Keeping it on your computer long term will leave you with an obsolete computer. Windows 10 has numerous problems, but lack of support soon is not one of them.

Comparable specification Windows 10 computers from multiple manufacturers can have very different performance between them.

You should be aware that anywhere that a ground rod is installed, that there may be AC voltage/current/frequency in the vicinity of it.

Windows 10 on both an old 2011 upgraded computer and a new 2016 computer was an excruciating experience
